Lotrel Overview
Lotrel is a combination blood pressure medication that contains two active ingredients: amlodipine (a calcium channel blocker) and benazepril (an ACE inhibitor). Together, these drugs work to lower high blood pressure through different mechanisms, making them more effective together than either one alone.
Amlodipine relaxes the smooth muscles in your blood vessels, allowing blood to flow more easily and reducing the pressure on vessel walls. Benazepril works by blocking an enzyme that causes blood vessels to narrow, which helps keep them open and flexible. By combining these two approaches, Lotrel provides comprehensive blood pressure control that can help protect your heart, kidneys, and brain from damage caused by hypertension.
Doctors prescribe Lotrel to patients who need stronger blood pressure control than a single medication provides. It's often used when initial treatment with one drug hasn't brought blood pressure down enough. Lotrel is a cost-effective alternative to brand-name drugs and offers the same effectiveness as the brand-name version at a lower price. The combination format also makes it easier to remember to take your medication, since you only need one pill instead of two.

Side Effects
Lotrel is generally well-tolerated by most people, but like all medications, it can cause side effects. Most side effects are mild and may improve as your body adjusts to the medication.
Common Side Effects
Dizziness or lightheadedness — May occur especially when you first start taking the medication or when standing up quickly from sitting or lying down
Persistent dry cough — One of the most common side effects of ACE inhibitors; usually harmless but can be bothersome
Swelling in feet, ankles, or hands — Caused by fluid retention; more common with the amlodipine component
Headache — Usually mild and temporary as your body adjusts to the medication
Fatigue or weakness — Some people feel more tired than usual when starting this medication
Flushed or warm skin — A mild flushing sensation, particularly in the face and neck area
Serious Side Effects
Severe allergic reaction — Includes difficulty breathing, swelling of the face or throat, or severe rash; requires immediate medical attention
Chest pain or pressure — May indicate a heart problem and needs urgent evaluation
Severe dizziness or fainting — Could mean your blood pressure has dropped too low
Irregular or racing heartbeat — Any unusual heart rhythm changes should be reported to your doctor
Signs of kidney problems — Including changes in urination, swelling, or unusual weight gain
When to Seek Medical Attention
Contact your doctor if you experience persistent cough that doesn't improve, unusual swelling in your extremities, or signs of an allergic reaction. While many side effects are minor, sudden chest pain, difficulty breathing, or fainting require immediate medical evaluation. Don't stop taking your medication without speaking to your healthcare provider, as suddenly stopping blood pressure medication can cause dangerous spikes in blood pressure.

Important: If you miss a dose, take it as soon as you remember, unless it's almost time for your next dose—then skip the missed dose. Never double up on doses. Do not stop taking Lotrel without consulting your doctor, even if you feel better, as blood pressure control requires consistent medication use.
Drug Interactions
Lotrel can interact with other medications, supplements, and substances. These interactions may reduce how well Lotrel works or increase your risk of side effects. Always tell your doctor about all medications and supplements you're taking.
Potassium Supplements and Potassium-Sparing Diuretics
Benazepril can raise your potassium levels, and combining it with potassium supplements or certain water pills (like spironolactone) may cause dangerously high potassium levels. Your doctor may need to monitor your potassium levels with blood tests.
NSAIDs (Ibuprofen, Naproxen)
Taking these pain relievers regularly with Lotrel may reduce the blood pressure-lowering effect and increase your risk of kidney problems. Use NSAIDs only occasionally and with your doctor's approval.
Lithium
Benazepril can increase lithium levels in your body, potentially causing toxicity. If you take lithium for bipolar disorder, your doctor will monitor lithium levels closely and may adjust your dose.
Diuretics (Water Pills)
Combining Lotrel with other diuretics may cause excessive blood pressure dropping or electrolyte imbalances. Your doctor will adjust your doses carefully if you need both medications.
Certain Blood Pressure Medications
Taking Lotrel with other ACE inhibitors or angiotensin receptor blockers (ARBs) increases the risk of low potassium, low blood pressure, and kidney problems. Your doctor won't typically prescribe these combinations.

Frequently Asked Questions
Get answers to common questions about Lotrel.
Yes, but you need careful monitoring. Lotrel can affect blood sugar levels and kidney function in people with diabetes. Your doctor will monitor your blood glucose and kidney function with regular blood tests. You may need adjustments to your diabetes medications or Lotrel dose, but many diabetic patients take Lotrel successfully with proper supervision.
A dry cough is a common side effect of ACE inhibitors like benazepril, affecting up to 20% of patients. This happens because ACE inhibitors affect a chemical in your body that influences coughing. If the cough becomes bothersome, your doctor may switch you to an angiotensin receptor blocker (ARB) instead, which causes cough less often.
Yes, generic versions contain the exact same active ingredients in the same doses. Generic and brand-name drugs are equally effective according to FDA standards. The main difference is price—generic versions cost significantly less. Both work identically in your body and provide the same blood pressure-lowering benefits.
No, you should not stop taking Lotrel without your doctor's approval, even if your blood pressure is well-controlled. Stopping suddenly can cause your blood pressure to spike dangerously and increase your risk of heart attack or stroke. If you're concerned about long-term use, discuss your options with your doctor rather than stopping on your own.
Generic Lotrel typically costs 80-90% less than brand-name Lotrel. Many pharmacy discount programs and insurance plans offer additional savings. You can save money on generic drugs for high blood pressure by comparing prices at different pharmacies or using generic discount programs at major retailers.
The Bottom Line
Lotrel combines two powerful blood pressure medications into one convenient daily pill, making it easier to manage high blood pressure and reduce your risk of serious complications like heart disease and stroke. The combination of amlodipine and benazepril addresses hypertension from multiple angles, often providing better control than either medication alone. While side effects like cough and swelling can occur, most people tolerate Lotrel well, and the benefits of controlled blood pressure typically outweigh minor inconveniences. Generic versions offer the same effectiveness at a fraction of the cost, making treatment more affordable and accessible. Taking Lotrel consistently as prescribed, along with regular blood pressure monitoring and lifestyle improvements, can significantly improve your long-term health outcomes.
